High-Throughput Phenotyping for Agronomic Traits in Cassava Using Aerial Imaging.

Large-scale phenotyping using unmanned aerial vehicles (UAVs) has been considered an important tool for plant selection. This study aimed to estimate the correlations between agronomic data and vegetation indices (VIs) obtained at different flight heights and to select prediction models to evaluate the potential use of aerial imaging in cassava breeding programs. Various VIs were obtained and analyzed using mixed models to derive the best linear unbiased predictors, heritability parameters, and correlations with various agronomic traits.

Cascade reservoirs affect mercury concentrations in fish from Teles Pires river, Brazilian Amazon.

Hydroelectric reservoirs favor mercury contamination in biota, but the contamination in cascade reservoirs is not yet clear. We investigated total mercury (THg) contamination in fish in four cascade reservoirs in the Brazilian Amazon between August 2022 and April 2023. Overall, downstream predatory fish showed higher mercury concentrations than those upstream.

Creeping fat and gut microbiota in Crohn's disease.

In this article, we explored the role of adipose tissue, especially mesenteric adipose tissue and creeping fat, and its association with the gut microbiota in the pathophysiology and progression of Crohn's disease (CD). CD is a form of inflammatory bowel disease characterized by chronic inflammation of the gastrointestinal tract, influenced by genetic predisposition, gut microbiota dysbiosis, and environmental factors. Gut microbiota plays a crucial role in modulating immune response and intestinal inflammation and is associated with the onset and progression of CD.

Pharmacological inhibition of key metabolic pathways attenuates Leishmania spp infection in macrophages.

Macrophages represent a fundamental component of the innate immune system that play a critical role in detecting and responding to pathogens as well as danger signals. Leishmania spp. infections lead to a notable alteration in macrophage metabolism, whereby infected cells display heightened energy metabolism that is linked to the integrity of host mitochondria.
